Do I need to run new wiring, or does the switch tap into existing circuits?

The switch comes integrated with the assembly, but confirm your vehicle's electrical setup before installation. Factory fog light locations typically have pre-routed harness channels—your manual will show what's already in place.

Will these work as plug-and-play, or do I need a relay and fuse setup?

The assembly ships ready to mount at factory points. Wiring configuration depends on your existing electrical infrastructure—test-fit and verify routing before final connections to avoid rewiring.

Can these be returned if they don't fit my specific year?

Fitment is confirmed at the point of sale—verify your model before checkout. If there's a mismatch after delivery, contact support with photos of your mounting area for return guidance.
